The tenth part of the column on standards relevant to transformers covers a list of standards for the raw materials used in the manufacturing of the active parts of transformers. These standards are relevant to all engineers working in the field of transformer design and manufacturing.

The active part of transformers is made from many processed raw materials like insulated copper conductors, electrical steel laminations, structural steel parts, electrical papers, pressboard, industrial plastic materials, paint, glues, and gaskets. The outer tank is fabricated from ferrous materials and surface protection is provided by various types of paints. National standards are available for these materials and this part of the column covers such relevant standards necessary for transformer engineers.
